Dimorphic forms. The distinctions between these have been pointed out above in 

 describin"; tlio markin<i;s of the wings. No reference has been made to the form 

 piasus. as it is wholly Pacilic, but its range will be mentioned further on, and the poly- 

 morphism of the species discussed. 



Aberrations. C. p. kit.mida. The intensest amount of markings on llie uiuler surface 

 of the hind wings of this species is reached in imlividuals (the so-called form margiuata) 

 where the outer border is margined with a broad, fuliginous border having a distinctly 

 crenulate interior edge and enclosing a series of submarginal dots, and in which the 

 whole disc of the wing is covered with an extensive, fuliginous patch, including all 

 the spots, excepting those on the inner border, which thus become, to a greater or less 

 extent, suflused together. In a single (J in the collection of Mr. Roland Thaxter, the 

 extent of these fuliginous markings is so great that the spots on the inner margin .also 

 are included, and the whole wing is fuliginous (paler along the nervules) excepting a 

 small basal patch crossing the entire wing, and a transverse, interrupted, ratlier nar- 

 row, arcuate, silvery gray band, narrowing from above downward, margined on either 

 side with blackish fuscous, running snbparallel to the outer border of the wing, and 

 at fully two interspace's distance from it. That this is truly a suflused variety is 

 plain from the extreme narrowness, comparatively speaking, of the silvery gray band, 

 and from the fact that on the fore wing not only is the fuliginous outer border of 

 rather more than excessive breadth, but the extra-mesial spots are broadened, more or 

 less blended, rather fuliginous than blackish, and those of the median interspaces 

 acconipanie<l by elongate, broad blotches of faint fuliginous, tilling almost the entire 

 remainder of the interspaces, toward the base of the wing. The fringe is less dis- 

 tinctly alternate than usual, the darker color being much in excess. The expanse of 

 this specimen is 30 mm. 



C. p. PSEUDORA. In the collection of the Boston Society of Natural History is a ? 

 specimen of this species collected at Milford, N. H., on May 23d, by Mr. Sanborn, 

 which ditt'ers from the normal $ in a peculiar manner. The upper surface varies 

 only as we may expect occasionally to happen, the basal two-thirds of the costal border 

 being heavily specked with violet, and the outer portion of the hind scarcely show- 



•The figures after the dashes arc from indi\ iduals of typical pseudargiolus.
